ABSTRACT:
A circumferentially continuous printing plate, which has the advantage over clamp plates that a clamping arrangement and groove in a plate cylinder can be eliminated, is formed by rolling a flat printing plate into tubular or sleeve form and welding the end edges together, preferably by a neodymium-YAG laser weld, resulting in a narrow, less than 1 mm wide, weld seam (2) having upper and lower concave sides, or by adhering the end edges to an underlay saddle (9), the plate can be coated and imaged when flat or after having been rolled and installed on a plate cylinder (37) of a printing machine. Interengaging projection-and-recess elements (4, 6; 14, 16) are formed on the plate (1, 1') and on the cylinder (37), respectively, to ensure lateral and circumferential register.
